Nemesia plant named &#39;pencand&#39;

ABSTRACT

A new and distinct cultivar of Nemesia plant named ‘Pencand’ that is characterized by a trailing, compact habit, dense upright spikes of fragrant purple-pink flowers and light green leaves. In combination these characteristics set ‘Pencand’ apart from all other existing varieties of Nemesia known to the inventor.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a new and distinct cultivar of Nemesia plant that will be referred to hereinafter by the cultivar name ‘Pencand’. ‘Pencand’ is a hybrid that resulted from a long term breeding program, involving cross-pollination of unidentified Nemesia hybrids, and was selected by the inventor in a cultivated area of Netherwent, Wales in 1996. The female parent is an unidentified Nemesia hybrid and the male parent is an unidentified Nemesia hybrid.

[0002] The breeding program began eight years ago with the objectives of improving upon such well-known varieties of Nemesia as ‘Confetti’, ‘Innocence’ and ‘Joan Wilder’. The inventor sought to first improve on habit by breeding plants that are more compact with stiff, upright flower stalks. Secondly the inventor sought to increase the size of the flower and the length of flowering time, and thirdly to improve the color range by producing clear colors. The fourth objective was to convert the species to a more efficient vegetative propagation rather than rely on seed, which is inherently unstable.

[0003] In 1995 the breeder made intervarietal and interspecific crosses with such common varieties as ‘Confetti’, ‘Innocence’, ‘Joan Wilder’, ‘Woodcote’ (all of these are unpatented), and unidentified seedlings from a cultivated area of Netherwent, Wales that had resulted from uncontrolled crosses. The inventor selected from the flowering plants those that showed increasing expression of the desired traits. Re-selection, back-crossing and new crossing was conducted to produce parent lines which could then be crossed to produce the final product.

[0004] ‘Pencand’ is distinguished from all other Nemesia known to the inventor by its trailing, compact habit, pink flowers, and dense fragrant flower spikes. The leaves are lanceolate in shape, and exhibit thicker tissue. Mature stems grow in square shape rather than round stems. The flower color exhibited by ‘Pencand’ contains purple hues, which is not seen in any other trailing, mounding Nemesia known to the inventor.

[0005] ‘Pencand’ was first asexually propagated by the inventor in 1997 in Netherwent, Wales using vegetative cuttings. It has been found stable and true to type after many cycles of vegetative cuttings.

SUMMARY OF THE INVENTION

[0006] The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘Pencand’. In combinaton these traits set the new cultivar apart from all other existing varieties of Nemesia known to the inventor. ‘Pencand’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.

[0007] 1. Nemesia ‘Pencand’ exhibits a trailing, mounding and compact habit.

[0008] 2. Nemesia ‘Pencand’ exhibits fragrant flowers that are purple-pink in color.

[0009] 3. Nemesia ‘Pencand’ exhibits upright flower spikes.

[0010] 4. Nemesia ‘Pencand’ is floriferous and exhibits large, repeat-flowering heads.

[0011] 5. Nemesia ‘Pencand’ is hardy to minus 5° Centigrade.

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The accompanying drawings illustrate the distinguishing traits and overall appearance of the new Nemesia cultivar ‘Pencand’. The plants are 4 months old, in 4-inch containers and were grown under greenhouse conditions in San Diego, Calif. Sheet 1 illustrates the entire plants, habit and flowers from a side perspective. Sheet 2 is a close-up view of the flower. The drawings were made using conventional photographic techniques. Although colors may appear different from actual colors due to light reflectance, they are as accurate as possible by conventional photography.
